T @ZZ 'Lu/wm' t may concern,.-

Be it known that I, LEONARD O. PULLEN, a citizen of the United States,residing at Augusta, in the county of Kennebecand State of Maine, haveinvented certain new and useful Improvements in Trolleys, of which thefollowing is a specification.

My invention relates to trolleyrpoles and stands for electric cars, andhas for its object I04 the provision of means for catching thetrolley-pole should the wheel leave the wire or should the rope thatholds it in an inoperative position break. In the trolleys as at presentconstructed when the wheel leaves the wire they fly upward, endangeringthe guy-wires, &c.', until the car is stopped; and my invention isintended to prevent the pole flying up in such emergencies, so that theoverhead .structures are vnot damaged and the necessity forstoppingthecar averted. l

. The construction 'and advantages of my invention will fully appearhereinafter and by reference to the accompanying drawing, which shows atrolley stand and pole, partly in section, constructed in accordancewith my invention.

. 1 represents asuitable base-plate secured to the roof ofthe car andhaving a circular groove 2 formed therein, in which rest antifrictio'nrollers or balls 3.

-4 represents the base of the trolley-stand, which is revolubly mountedon base-plate 1 by means of bolt 5, which is placed in the center ofcircular'groove 2.

6 represents the pole-support, secured to base 4, on which is pvotallymounted, by rmeans of bolt 7 the pole-socket 8, made kof two parts heldtogether by bolts or screws, so as to admit of their being readilydismembered.

9 represents a segmental ratchet formed on the top and rear of support6, and 10 a pawl slidably mounted in socket 11, formed by making achannel in each of the two parts of polesocket 8. f

12 represents a spring to actuatepawl 10, mounted on reduced portion 13of the pawl and'bearing between a shoulder 14 on one of the parts of thesocket and a nut 15, mounted on screw-threads 16` on said reducedportion 13, the purpose of nut 15V being to permit the tension of spring12 to beregulated as desired. 17 represents the"trolley-pole, adapted toseat in socket 8 and held therein by means of straps 18, secured to eachpart of said socket and held together by means ofbolts 19.

' 2O represents the trolley-head, pivoted in the other end of thetrolley-pole, having a trolleywheel 21 journaled in its outer end, and22 the rope foroperating the pole. The pole is made s'de of the socket.

The front of support 6 is extended, as shown at 27, and has slidablymounted thereon a block 28.

29 represents springs secured to block 28, and having their free endssecured to curved blocks 30, secured to the sides of socket 8. Thetension of .springs 29 is adjustable by means of a screw-rod 31,journaled in the shoulder 32 on the extended end 27 of support 6 andhaving its screw-threaded portion intermemberi-ng with a screw-threadedbore in'said block.

In ope-ration the trolley-pole may be ad- 12, and as the tension 0fsprings 29 is greater than that of spring 12 the trolley-head when inposition against the line-wire will be de- --justed by means'of rope 22,a slight pull being V.necessary to overcome the tension of. springVention may be used to hold the trolley-pole in an inoperative positionb y pulling the pole down and suddenly letting go of the rope.

Having thus described my invention, what I claim is- 1. In a trolley, atrolley-Stand having a segmental ratchet, a pole-socket pivotallymounted on said stand, a pawl slidably mounted in said socket, a springto vactuate said pawl, means to regulate the tension of said spring, thepole secured in said socket, the trolleyhead pivotally mounted on thefree end of said pole, and means to connect said pawl and head,substantially as shown and described.

2. In a trolley, a trolley-stand having a segmental ratchet, apole-socket pivotally mounted on said stand, a pawl slidably mounted insaid socket having a reduced portion, screwthreads on said reducedportion, a nut engaging said screw-threads, a spring mounted on saidreduced portion and bearing between said nut and shoulder on the socket,the pole secured in the socket, the trolley-head pivotally mounted onthe free end of the trolley-pole, and means to connect said pawl andhead, substantially as shown and described.

3. In a trolley, a trolley-stand having a segmental ratchet, apole-socket pivotally mounted on said stand, a paw] slidably mounted insaid socket having a reduced portion and provided with a bore, a spring'to actuatc said pawl, means to regulate the tension of said spring, thepole secured in said socket, the trolley-head pivotally mounted on thefree end of said pole, and a rod secured to said trolleyhead and in thebore of said pawl, substantially as shown and described.

A. In a trolley, a trolley-stand having a segmental ratchet, apole-socket pivotall y mounted on said stand, a pawl slidably mounted insaid socket havinga reduced portion and provided with a bore,screw-threads on said reduced portion, a nut engaging' saidscrewthreads, a spring mounted on said reduced portion and bearingbetween said nut and a shoulder on the socket, a tubular pole secured inthe socket, the trolley-head pivotally secured in the free end of thepole, arod pivotally secured to the trolley-head and adapted to beinserted in the bore in the pawl, and a set-screw to hold the rod insaid pawl, substantially as shown and described.

In testimony whereofI l hereto ailix my signature in the presence of twowitnesses.

LEONARD O. IULLEN.
